In more than 60 years of providing construction cost data to the industry, BCIS has a proud track record of driving innovation. This month we’re marking 40 years since we launched our first online service for subscribers.
Although the World Wide Web would not be invented for another five years, from April 1984 BCIS offered subscribers a direct connection to its database using modems and the telephone line.
In this way, subscribers could access project analyses dating back to 1973 – analyses that are still accessible on the BCIS service today. To make use of the analyses, BCIS also provided background information and a range of indices.
The four BCIS dial-up modems, which enabled four subscribers to connect at the same time had a transmission speed of 1,200 baud, equivalent to 0.001 Mbps and around 120 characters per second.
Lead Consultant Joe Martin joined BCIS in 1971 after working as a quantity surveyor at Franklin + Andrews.
He said: ‘Much of the history of BCIS is aligned with computerisation. When BCIS Online was launched in 1984 it was a joint venture with PSA, the Property Service Agency, which managed all centrally held public sector buildings and works.
‘The BCIS database also held the PSA information and, with the privatisation of the PSA, we retained both the public and private sector data. From then we have been constantly developing our online offering.’
Largely responsible for the research and initial efforts to ‘go online’ was Ian Pegg, who joined BCIS after graduation in 1977 and is now Data Solutions Architect.
He said: ‘There was no computer when I arrived, just an up-market Texas Instruments calculator. The first computer we had for internal use only, in around 1979, was a NorthStar Horizon, which was a desktop box with a separate monitor. It had an 8-bit processor and came with twin 150Kb floppy disc drives and 48K of RAM.
‘The computer purchased to host the online service, and perform background processing on BCIS data, was a PDP 11/44, which was a floor-standing unit about the size of two three-drawer filing cabinets. The software used to interrogate the system was originally written for a terminal with paper printout so, despite BCIS using VDUs, the text scrolled up the screen.
‘It was innovative at the time because we were encouraging users to download our data to their own computers when most online databases were trying to prevent users from taking electronic copies of their data. The computer that subscribers needed to access the service was a CP/M microcomputer, which had an 8-bit processer and, if you were lucky, 64Kb of memory.’
